One of my passions is researching Australian motoring history, and finding out information about obscure cars, bikes and other things. The online newspaper collection at the National Library of Australia has made it easier to find out really good information.
An example is the 1920 “Aussi Also” motorcycle, which I first discovered while reading Robert Saward’s excellent book, “A-Z of Australian-Made Motorcycles: 1893-1942”, Turton & Armstrong, Sydney, 1996 ISBN: 0-908031-64-5.
I did a search on the NLA website, and found excellent contemporary coverage, including this excellent advertisement. It was a shame that the company folded before any production occurred.
